Security Incident & Vulnerability Management Consultant
(Operational Integrator / SIAM - Transition Role)

UK Sole National ONLY
Security Clearance required

Role Summary
The Security Incident & Vulnerability Management Consultant operates within the Operational Integrator (OI) function to support the transition to a multi-supplier (SIAM) model within a Defence environment.
The role focuses on understanding, aligning and governing existing high-severity security incident management (S3/S4) and vulnerability management processes across suppliers. Ensuring a consistent, risk-based approach in line with client policy and regulatory requirements, supported by appropriate evidence.
The outcome is a coherent, evidence-driven view of security risk, covering both active incidents and underlying vulnerabilities, with processes standardised and ready for BAU handover.
This is a governance and coordination role, not a hands-on SOC, incident response, or vulnerability remediation function.

Key Responsibilities

• Align and standardise supplier processes for high-severity incidents (S3/S4) and vulnerability management.
• Establish governance for incident severity, escalation, vulnerability prioritisation (CVSS, KEV, EPSS), and risk acceptance.
• Coordinate multiple suppliers to ensure consistent delivery and compliance.
• Govern major incident lifecycle activities, including escalation, communication, reporting, and assurance.
• Oversee vulnerability management from identification through remediation and closure.
• Define audit-ready evidence requirements and ensure alignment with ISMS and control frameworks.
• Deliver governance reporting and support transition to BAU operations.

Essential Skills & Experience

• Experience in Cyber Security Governance, Incident Management, or Vulnerability Management.
• Strong understanding of incident response and vulnerability management lifecycles.
• Experience working within multi-supplier or SIAM environments.
• Ability to interpret and govern SOC and vulnerability management outputs.

• Knowledge of NIST CSF, NCSC guidance, or UK Government security frameorks.
• Experience within Defence or other highly regulated environments.
• Exposure to ISMS, audit, assurance, and ITIL practices.
